Figure 2-14: A 1–line sweep rate with 15 continuous lines (from mid field)
displayed using LINE SELECT.
Push and hold the SWEEP button until the front–panel 1LINE indicator lights.
Look for a display of one line, with a readout that shows F1 or F2:131 over 15
(see Figure 2-14). This is the 15 continuous lines which were intensified in the
2–field display, overlayed in a one–line display. The readout shows that these 15
lines are in field 1 or field 2, starting with line 131. Change the field by pushing
the FIELD button. Turn off LINE SELECT.
